Here is a look at the 1983 bombing of a Marine compound in Beirut, Lebanon, that killed 241 US service personnel.
On October 23, 1983, 241 US service personnel – including 220 Marines and 21 other service personnel – are killed by a truck bomb at a Marine compound in Beirut, Lebanon.
Three hundred service members had been living at the four-story building at the airport in Beirut. There were 1,800 Marines stationed in Beirut at the time.
A multi-national force with units from France, Italy and the United Kingdom was also on peacekeeping duty in Lebanon at the same time.
At the same time the Marine barracks was hit, a suicide bomber drove a pickup truck full of explosives and crashed into a building housing French paratroopers. Approximately 58 French soldiers were killed in the attack.
This was the deadliest attack against US Marines since the battle over Iwo Jima in 1945.
The Marines were criticized for having lax security at the barracks.
The commander of the barracks, Col. Timothy J. Geraghty, said in congressional hearings investigating the attacks that the compound was hard to defend because it was on flat ground and vehicles drove by it daily to access the airport.
